PeterDonis said:Can you be more specific about the boundary condition you have in mind? I assume it's at the horizon, because the boundary condition at spatial infinity is the same (asymptotic flatness). But I'm not sure I would characterize the presence of a coordinate singularity at the horizon in SC coordinates as a "boundary condition", and I'm not sure what else you could be referring to.

I'm referring simply to the fact that you require r>Rs, else you have coordinate patch of a TBD complete solution rather than a complete solution. This is a boundary condition.
